Serial No. 486,788.

To all whom it may 0011 com Be it known that I, REME A. BEAUSEJOUR, asubject of the King of Great Britain, and resident of the borough ofBrooklyn, in thecity and State of New York, have invented a new anduseful Holder for Liquid-Coating Machines, of which the following is aspecification.

This invention relates to that type of liquid coating machines in whichthe articles to be treated to a liquid coating are held in an articleholder and raised and lowered by Huid actuated means, the parts being soconstructed, arranged and operated that the articles being treated areso held that the liquid dripping therefrom will be kept fromaccumulating on any surface of the articles, and the articles will beuniformly coated.

One object is to provide means for steadying the lifting mechanism, sothat the operations of raising or lowering may be accomplished withoutany vibration or trembling of the article holder.

Another object is to provide an improved means for retaining thearticles to be coated in the holder.

A further object is to provide improved means for securing the holder tothe lifting mechanism.

A practical embodimentof my invention is represented in the accompanyingdrawings, in which- Figure 1 represents in side elevation, partially insection, an embodiment of my invention as applied to a single dippingtank, the parts being shown in their lowered positions in full lines andin their raised positions in dotted lines, Fig. 2 is a top plan view ofthe same, Figs. 3, 4 and 5 are enlarged detail front, side and top planviews, respectively, of the means for carrying the article holder andthe means for retaining it in its gravitational position, Fig. 6 is avertical section of the means for locking the holder to the carryingmeans taken in the plane of the line A-A of Fig. 4, Fig. 7 is a sectionin the plane of the line B-B of Fig. 4, looking in the direction of thearrows, F ig. S is an end view of an embodiment of my invention,partially in section, the parts being shown in their lowered position,Fig. 9 is a detail front view of the means for engaging and supportingthe upper portions of the articles being treated, Fig. 10 is a sectiontaken in the plane of the line C-C of Fig. 9, looking in the directionof t-he arrows, Fig. 11 is an inverted plan view of the article holder,F ig. 12 is a plan view of the same, the parts being broken away, Fig.13 is a detail side view partially in section of one of the ,clamps forsupporting the lower portions of the articles being treated, and itssupport, and Fig. 14 is a front View of the same.

The dipping tank is denoted by 1 and is herein shown as provided with afloor or other support 2 at its bottom, and a platform 3 near its top.The cylinder 4 of a Huid actuated device is located adjacent to thetank 1. A piston 5 is fitted to reciprocate within the cylinder, 4, andits rod 6 extends upwardly through the top of the cylinder.

The fluid inlet pipe is indicated by 7 and it has a pressure regulator 8and a pressure regulator gage 9 therein. This inlet pipe 7 is providedwith a branch pipe l0 leading to the upper end of the cylinder 4 andanother branch pipe 11 leading to the lower end of said cylinder. Theiuid outlet pipe 12 is connected to the branch pipe l0 through a pipe 13having a manually operated valve 14 therein. This outletpipe 12 is alsoconnected to the branch pipe 11, through a pipe 15 having a manuallyoperated valve 16 therein. A manually operated valve 17 is located inthe branch inlet pipe l1, and a manually operated valve 18 is located inthe inlet pipe 7.

A bracket is carried by the piston rod 6, above the cylinder 4,whichbracket comprises a tubular post 19 surrounding a piston rod 6 andhavin@ a horizontal arm 20 projecting from its Tower end; and adiagonally arranged supporting strap 21 eX- tending from its upper endto the horizontal arm 20 at a point between its inner and outer ends. Avertical post 22 is arranged adjacent to the cylinder 4, which post isof suticient height to extend above the top of the bracket when thelatter is in its raised position. The top of the post is rigidly securedto an upper support 22* and its bottom rests in a suitable support 4* onthe cylinder 4. A pulley 23 is mounted at the top of the -post 22, overwhich pulley runs the Hexible connection 24 of a bracketcounterbalancing device; one end of which flexible connection isattached to the top of the tubular post 19 and the other end to acounterbalanced weight 25. To insure an even vertical movement of thebracket, I provide upper and lower guide pieces 26 mounted on thetubular post 19 and each carrying a pair of rollers 27 which engage thepost 22 on opposite sides thereof thus causing the tubular post 19 toremain exactly Iparallel with the post 22 during the vertical movementsof the bracket. For this salne purpose and to absolutely prevent anywabbling or vibration of the bracket as it is raised or lowered, Iprovide a support for the outer end of the horizontal arm 2O which isarranged in the following manner: A flexible connection 28 is attachedto the outer end of the horizontal arm 20. It then passes over thepulley 29 conveniently mounted on a suitable upper support 29* directlyover the end of the arm 20; thence over the pulley 23; thence over thepulley 30 mounted in the horizontal lug 31 on the upper part of the post22; thence over the pulley 32 mounted on the horizontal lug 33 near thebottom of the post 22; thence over one of the lower rollers 27; and isthen attached to the upper guide piece 26. This flexible connection 28is drawn taut with the arm 20 exactly at right angles to the tubularpost 19, and serves admirably as a support for the arm 20 to prevent anytrembling of the bracket in its vertical movements, which tremors mightbe imparted to the article being coated and mar the article. Thehorizontal arm 2() is of inverted U-shape in its cross section, asclearly shown in Fig. 4, with its edges 34, 35 turned in toward eachother substantially at right angles to the side of the arm.

A carriage 36 is fitted to reciprocate within the arm 20, and it issupported therein by the wheels 37 arranged to ride on the inturnededges 34, 35, of the arm. Any suitable means, such, for instance, as thepins 20* and 20M serve to limit the outward and inward movements of thecarriage.

The article holder comprises a skeleton frame having vertical side bars3S and diagonal side bars 39 connecting the top 40 and the bottom 41.The top of the holder is provided with a plate 42 (Fig. 4) having a holetherein for receiving the sna-p catches 43 carried by the depending arm44 of the carriage 36 for locking the article holder in engagement withthe said carriage. For releasing the snap catches 43 from theirengagement with the plate 42 I provide a device comprising a loop 45 andwedges 46. This device is pivoted to the arm 44 in such a position thata swinging movement to the right (Fig. 4) will cause the wedges 46 topass between the snap catches 43 and the arm 44 thus disengaging thecatches from the plate 42.

A spring pressed latch 47 1s hinged at 48 to a 'projection 49 on thelateral arm 2O of the bracket; which latch is provided with a verticalseries of catches 50 arranged to receive in one of them a tooth 51 onthe top of an article holder', according to the inclination which theholder assumes under the influence of the weight and disposition of thearticles to be dipped. This tooth 51 is part of a notch 51* forreceiving the spring pressed latch 47 to automatically retain the holderin its proper position longitudinally of the arm 20. The lower end ofthis latch 47 is provided with a cam 52 which is arranged in position tobe engaged by the pin 53 carried by the top of the holder whereby thesaid latch is removed from its engagement with the tooth 51 and notch5l* of the holder, as the latter is slid longitudinally of the arm 20 ofthe bracket to be removed from its position over the tank. The functionof this spring pressed latch is to retain the article holder against anyswinging movement while it is being lowered or raised, and also toautomatically arrestI the movement of thel holder in either directionlongitudinally of the arm 20 after the holder has reached its properposition over the tank. To further insure against any swinging movementof the holder, I provide a plurality of series of props 54 pivoted to aprojection 55 on the horizontal arm 20. These props are of variouslengths and so arranged that when the holder has assumed the inclinationcontrolled by the center of gravity of the holder and articles thereinto be dipped, the prop of the proper length will swing its lower endinto engagement with the top of the holder. Thus the props 54 coperatewith the latch 47 to retain the article holder absolutely against anyswinging motion in the tank. The article holder' itself is shown hereinas particularly well adapted for use in holding the several parts or' apiano, The bottom 41 of the holder is provided with a plurality oflaterally extended cross bars 56 which form supports for the bottoms ofthe articles to be dipped. Across bar 57 extends between the side bars39 of the holder, a short distance above the bottom 41. On one or moreof these cross bars I provide spring clamps 58 so arranged that theywill clamp the several articles to the holder.

The diagonal side bars 39 are provided near their tops with loop frames59. These frames have holes 60 litted to register with any one of aseries of holes 61 in the bars 39, and the trames may be secured indifferent adjustments on said bars by means ot' the bolts 62 and wingednuts 63. Each one ot these loop frames is provided with a series ofspring pressed lingers 64, having pointed ends arranged to engage thetops of the articles to be dipped; the said fin-- gers passing throughboth horizontal members of the loop frames and having a sliding movementtherein. Pins 64* serve to limit the downward movement of the fingers.Each of the fingers is provided with a pulley 65 near its upper end; andpulleys 66 are mounted in the frame intermediate the lingers. A flexibleconnection 67 passes around each of the pulleys, both ends of whichflexible connection are attached to springs 68, mounted in the framenear the ends thereof for tending to hold the fingers at the limit oftheir inward movement. By this construction I obtain an even pressure onall the fingers and eliminate the necessity of providing an individualspring for each finger.

The positions of the several article holder devices are suoli that thearticles are so held that the liquid in dripping therefrom will runalong an edge to a corner and drop therefrom, thus avoiding anystreaking of the article or unevenness of the coating.

For supporting the article holder when it is removed from the dippingmechanism, and facilitating its removal from one place to another, Iprovide small ball bearing casters 69 and large ball bearing casters 70which may be removably secured to the bottom 41 of the holder by meansof clamp screws 71. I preferably arrange the small casters approximatelyat the corners of the bottom of the holder and the large casters aboutcentrally of the long sides of the arm, as shown in Fig. 11. Vhen theholder is at rest on the casters, it will be supported by the two largecasters 70 and the two small casters 69 at either end of the bottom,according as the center of gravity of the holder and articles containedtherein is at one side or the other of the large casters. My object inproviding two large casters is to facilitate the turning about of theholder as it is rolled from one place to another. This turning is veryeasily accomplished if the holder is first balanced on the two largecasters only.

In operation, presupposing the fluid to have been admitted to the underside of the piston 5 and permitted to escape from the upper side thereoffor causing the piston rod and the bracket thereon to be raised to thelimit of its upward movement; the carriage 36 is moved out to the end ofthe horizontal arm 20 and the article holder secured thereto. Thearticles to be dipped are then carefully secured within the holder, andthe latter and the carriage from which it is suspended are movedinwardly to a position directly over the tank. The holder will seek itscenter of gravity as it is being moved along the arm 2() and the struts54 and latch 47 will automatically retain it in that position. The Huidis now admitted to the top of the piston 5 and permitted to escape fromthe bottom thereof,

thus forcing the bracket and the holder carried thereby downwardly forimmersing the article in the liquid in the tank. When it is desired toraise the articles from the tank, fluid is admitted to the under side ofthe piston 5 and permitted to escape from the upper side thereof, thuscausing the piston rod and the bracket thereon to slowly rise, and withthem the article holder. The guide pieces 26, with their rollers 27,engaging the post 22, in conjunction with the counterbalancing Weight 25and the flexible connection 28, insure an even vertical movement of thebracket and holder without the slightest degree of quivering ortrembling, thereby producing an absolutely smooth and even coating, andhence a very superior rfinish to the article. After the articles havebeen raised from the tank, and at the proper time, the carriage andholder may be moved outwardly along the arm 20 until the holder isbeyond the tank, the casters adjusted to the bottom of the holder, thelatter disengaged from the carriage and rolled to any desired location,where the articles may be allowed to dry.

While I have shown one form o-f uid actuating means for raising andlowering the article holder, it is to be understood that 1 contemplatethe use of any suitable means for accomplishing this result. It is alsoevident that changes may be resorted to in the form, arrangement andconstruction of the various parts of my invention without departing fromthe scope thereof, hence I do not wish to limit myself strictly to theform herein shown and described, but
